EG003-03 February 24, 2003 Title: SULFUR ODOR FROM EXHAUST Models: All Models Introduction Some owners of Toyota vehicles may experience a sulfur-like or "rotten egg" odor from the exhaust system. Sulfur is a natural component of crude oil from which gasoline is refined and the amount of sulfur can be decreased through the refining process. The amount of sulfur in fuel sold in California is regulated, however gasoline sold in other states can have substantially higher sulfur content. Sulfur content also varies considerably between gasoline brands and locations. Applicable Vehicles^ All Models. Repair Procedure A sulfur odor emitted from the vehicle's tailpipe does not necessarily indicate that there is an issue with the engine's running condition, but is most likely directly related to the fuel. ^ If the vehicle is exhibiting an excessive sulfur odor, the following checks should be performed: ^ If the MIL light is ON, check for DTCs and repair as necessary. If no trouble is found after performing the above check, recommend the customer try a different source of fuel. Replacement of oxygen sensors, air/fuel ratio sensors or catalytic converters will not reduce the odor and will therefore not be considered warrantable. Warranty Information |
Does anybody know if there is a newer or an updated TSB on the sulphur smell issue? This one (2003) says replacing different parts will not fix it and that it's not warranty work.
I just read a thread last night where a Skyak got his catalytic converters replaced under warranty on the sulphur TSB. http://www.toyota-4runner.org/showthread.php?t=87919 Any thoughts? |
I was having the same sulphur-smell issue. I called my local dealer with the TSB number, but he wanted to research it first. Turns out he came up with a different TSB (darn, I didn't ask for which one).
I brought the 4R in last week and got my catalytic converter replaced under the 80,000-mile Emissions Warranty. There are 1-2 air flow sensors installed in the converter; mine were stuck, so they ordered new ones and also covered those under warranty. Final bill would have been nearly $2,600. Honestly, now that it's done, I think I preferred how it smelled before. But I figure that since I got the parts replaced at 42K miles, these parts will just last me that much longer. My local mechanic said he'd charge me $100 to re-route the tailpipe off to the side, instead of out the back. I'll be doing that later this month. Hopefully that helps reduce the exhaust that gets sucked back into the cabin. |
Thanks for sharing!

Honestly, I don't know why Toyota didn't design it this way to begin with. (Ignore the scratches... they were my fault a long time ago, not from when the shop did the work.) :ybrick: |
